VALVE Filed Aug. 18, 19/28 2 Sheets-Shea! 2 Patented July 7, 1931 UNITED STATES PATENT OFFICE EMIL PRICE AND WILLIAM A. PFISTER, OF LOS ANGELES, CALIFORNIA VALVE Our invention relates to and has for a purpose the provision of a valve by which the flow of fluid from a plurality of sources can be controlled by a single actuator to cause the flow of fluid from one source to be discontinued and the fiow of fiuid from at least one other of the sources, permitted, or vice versa according as the actuator is moved to one poi sition or another.

,10 It is a further purpose of our invention to provide a valve of the above described character, which is particularly adapted, although not necessarily, for use in a combination bath and shower installation, and by which water can be diverted at will to discharge through one outlet, to the bath tub or discharge through another outlet to a shower head.

It is another purpose of our invention to 1; provide a diverting valve characterized by 2o the simplicity and durability of construction and the ease of operation from al single actuator, of its mechanism embodying a pairof valves controlling outlets from a chamber,

' g and having mountings in which the valves 26 are threaded reversely from each other, with the valves operatively connected to each other for rotation as a unit by the single actuator, and being so disposed relative to the respec- 1; tive outlets they control, that one valve will 30 close one outlet and the other valve will open the other outlet or vice versa., according as the valves are rotated as a unit in one direction or the other.

We will describe only one form of valve $5* embodying our invention and will then pointv out the novel features thereof in claims.

In the accompanying drawings Fig. 1 is a view showing in vertical longitudinal section one form of valve embodying 40 our invention, and illustrating one position occupied by the valve;

Fig. 2 is a view similar to Fig. 1 and illustrating another position of the valve; I Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1 and looking in the direction of the arrows;

Figs. 4 and 5 are sectional views taken respectively on the lines 4--4 and 5.--5 of Fig. 1 and 1o0king in the direction of the arrows.

Referring specifically to the drawings in which similar reference characters designate similar parts in each of the. several views, our invention in its broadest aspect contemplates the provision-of a valve by which the flow of fluid from a plurality of sources can be controlled by a single actuating' means to cause the flow of' fluid from one source t-o be discontinued and theflow of iiuid from at least one other of the sources, permitted, or vice versa according as the actuating means is moved to one position or another.

This broad principle of our invention is shown for the purpose of illustration embodied in a valve .particularly adapted for use in a combination bath and shower installation wherein it is required to divert hot or cold water or any mixture of the two to discharge from a suitable spout into the bath ubdor to discharge from a suitable-shower ea A lThis valve in its present embodiment comprises a valve body B constructed to provide therein a chamber C of cylindrical form, having a pair of' inlets 10 and 11 diametrically opposed and formed respectively by internally threaded nipples 12 and 13 to which are adapted to be connected, pipes 14 and 15 respectively, one of which leads from a source of cold water supply and the other from a source of hot 'water supply. Suitable valves (not shown) are adapted to be provided to control the flow of hot and cold waterfrom the pipes 14 and 15 tothe chamber C, to the end that either hot or cold water can be admitted to the chamber to the exclusion of the other, or any proportion of hot and cold water can be admitted to the chamber for mixing therein.

One end wall of the chamber C is open to l provide a port constituting an outlet 16 communicating with a passage 17 formed in thebody B and terminating in a nipple 18 to which is adapted to be connected a pipe 19 leading to a shower head (not shown) while the other end wall of the chamber is also open to provide a second port constituting an out-let 20 which communicates with the inte-A rior of a hollow cylindrical extension 21 forming part of the valve body B.

From a side of the extension 21 leads a pas be diverted .to .either the sage 22 terminating in a nipple 23 diametrically opposed to the nipple 18 and to which is adapted to be connected a pipe 24 leading to a suitable bath tub spout (not shown).

The outlets 2() and 16 are controlled by valves V and V respectively, which latter are adapted to be operated by a single actuating means designated generally at A, to close one outlet and open the other or vice versa so that water from the chamber C can pipe 19 or 24 .to the exclusion of the other.

The valve V in the present embodiment is in the form of a disk 25 recessed on one face to receive a gasket 26 .clamped to the disk by a nut 27 threaded on a reduced externally threaded projection 28 formed on the disk and extending through a central Opening in the gasket. The valve V is provided with i an externally threaded portion 29 threaded into a nut 30 in the forni oi' an internally threaded sleeve having a circular `flange 31 seating in an annular recess 32 formed in the extension 2l, the nut having a pair .ofdiametrically opposed lugs 33 vseating in grooves 34 formed in the wall of the extension 2l, to the end that the nut will be fixed against rotation inthe body B.

' The nut is clamped against endwise dise placement in the body by means of a cap 35 bearing against the 'flange 31 andthreaded into the open end of the extension as indicated at`38 to form a closure for the eXtension.

In the. cap 35 is a vconventional packing gland 37 through which extends a. stem 38 fixed at its inner end te' the threaded portion 29 oi' the valve V, and provided at its end with an operating knob 39, which with the stem 38 constitutes, in the present insta-nce, the actuating means A above referred to. It will be clear that rotation of vthe stem 38 in one direct-ion er the other will cause the valve V to be fed by the nut 30 in one direction or the other. Y

The valve V in the present instance is in the form of a disk to one face of which is secured by a screw 4Q, a gasket 41, the valve Vl having a portion 42 threaded externally and oppositely to the portion 29 of the valve V, the portion 42 being illustrated as provided with left hand threads and the portion 29 with right hand threads. l

The portion 42 of the valve V is threaded into a. nut 43in the form. of an open ended sleeve having an enlarged externally threaded -iiange 44 threaded into the wall of the opening in the chamber C constituting the outlet 20, the nat .extending into the chamberV C and being disposed in alinement with'the nut 30.' The nut 43 Vis provided with ai further enlarged flange 45 having' an angular wrench receivingI pocket 46 into which a suitable inst-ruinent is adapted to be inserted to screw the nut 43 suiiicientlytight to insure that it will be fixed against rotation in the body B. The nut 43 is provided with a circular series of openings or ports 47 through which Water from the chamber C can discharge therefrom through the nut into the extension 21 when the valve V is open.

The valve V is provided axially with a socket 48 non-circular in cross section and illustrated as being square, the socket slidably receiving a stein 49 projecting axially from the portion 42 .of the valve V so as to provide a splined connection between the valves by which the latter are operatively connected for rotary movement as a unit, yet can move towards 4or away from each other under the action of the reversely threaded nuts 30 and 43 according as ,the valves are rotated as a unit in one direction or the other. v:[t will be clear that the nuts 30 and 43 and the portions 29 and 42 of the valves V yand V res'pec, tively, broadly constitute al means by which the valve V is caused to close the outlet 16 and the valve V to open the outlet 20 or vice versa according as the'valves are rotated as a unit in one direction or the other, the valve V when inV closed position engaging an annular bead formed on the outer face of .the nut 43 and constituting an annular valve seat 50, and the valve V when in closed position engaging an annular bead formed' in the chamber C in ysurrounding relation to the outlet y16 and constituting an annular valve seat 51, to the end that when the valves oc-l cupy their closed positions a fluid-tight ,'oint will be eiiected between'the gaskets io the valves and the respective seats, Y .l In operation, it' will be clear that with the valve V ope-n andthe valve V closedras shown in Fig. 1, Water from the chamber C will be free to ilow through the ports 30 into the interior of the extension 21 and thence through the passage 212 into the pipe 24 to the bath tub spout as indicated by the arrowsV in this igurel However, upon rotating the knob 39 in the direction 'of the arrow 0L, Fig. 1, the valves V and V will be correspond:- ingly rotated as a unit through the medium of their operativeA connection, and will be fed towards each other as a result of the reverse threading of the nuts 30 and43 to cause the valve V to move to closed position and the valve V to open position as shown in Fig. 2. Vilater fromthechamber C will now discharge through the outlet 16 to the passage 17 and thence into the head. v
